...nding patch for the timeout mechanism to deal with the shared interrupt issue for vt-d enabled hvm guest. We modify the patch following your comments last time and make some other small fix: 1) We don''t touch the locking around the hvm_dpci_eoi(). 2) Remove the HZ from the TIME_OUT_PERIOD macro which may confuse others. 3) Add some explanation to the return value for the hvm_pci_intx_assert(), and the has_timer parameter for the hvm_dpci_eoi. We have tested it with shared interrupt between dom0/HVM(pcie/disk) and HVM/HVM(pcie/pcie). Signed-off-by: Xin, Xiaohui<xiaohui...

Attached is a patch for shared interrupt between dom0 and HVM domain for vtd. Most of problem is caused by that we should inject interrupt to both domains and the physical interrupt deassertion then may be delayed by the device assigned to the HVM. The patch adds a timer, and the time out value is sufficient large to tolerant the delaying used to wait for the physical interrupt deassertion.
